...ete novice! I am working with a large multivariate data set that has 10 explanatory environmental variables (e.g. temp, depth) and over 60 response variables (each is a separate species). My data frame is set up like the simplified version below: JulianDay Temperature Salinity Depth Copepod Barnacle Gastropod Bivalve 222 12.1 33 0.3 500 756 0 178 222 12.3 33.2 1.1 145 111 0 0 223 11.1...

Hi, I'm trying to create a plot showing the density distribution of some shipping data. I like the look of violin plots, but my data is not continuous but rather binned and I want to make sure its binned nature (not smooth) is apparent in the final plot. So for example, I have the number of individuals per vessel, but rather than having the actual number of individuals I have data in the

Hi there, I'm using the lattice package to create an xy plot of abundance vs. depth for 5 stages of barnacle larvae from 5 species. Each panel of the plot represents a different stage, while different loess smoothers within each panel should represent different species. However, I would like depth to be on the y-axis and abundance to be on the x-axis, because this is more intuitive as an oceanographer. T...

Hello Again R help readers - I have posted in the past and want to thank all those who replied with helpful suggestions. This regards mixed model anova, and the nlme package. My purpose is to make a comparison of barnacle recruit density from 3 different regions. In each of these regions i have sampled 6 randomly chosen sites. I sampled 20 quadrats at each site giving me a total sample size of 360. Thus i have as a design Response: density Factors: regions (3 levels, fixed) sites (18 levels, random) I started...
